My dog is coughing, spitting white foam, and won't eat. ER vet?

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 52 lbs

My dog is vaccinated for kennel cough, but may have been recently exposed when he was boarded this past weekend. I took him the vet last week and she said his lungs and heart sounded good. He’s still had a mild “cough” but today he’s begun spitting up a white foamy mucus. His other bodily functions have seen normal, and he ate breakfast like normal. But, isn’t interested in his dinner. Should I take him to the emergency room vet, or will I be OK to get him in tomorrow?

Poor Baxter! If he's isn't very lethargic or having trouble breathing, you can wait until the morning. If he become very lethargic or have trouble breathing, then I would take him into the ER vet now. Best of luck.
